a measure of the effectiveness of a batter at reaching base and advancing other runners, calculated as the sum of the number of bases reached on each hit, divided by the total number of times at bat. A double counts two bases, a triple three, a home run four. Thus a batter with four singles, two doubles and a triple in 20 official times at bat would have a
slugging average of 0.550, and a
batting average of 0.350. Also called
slugging percentage. Compare
batting average. [
